Sweden is a main extractor of natural resources, leading the exploitation of forestry in Europe. Forestry counts for ten percent of exported goods from Sweden and has the most significant trade balance of all industrial categories. Forestry is a branch that has remained traditional for a long time and has not actually been the focus for research in this field. Internal control is implemented in all Swedish companies to protect company assets and minimise risk. The aim of International business strategies is mainly to achieve success on the international market. Through a qualitative single case study, with empirical data extracted from interviews and observations, conclusions were drawn. The interaction between the two terms internal control and international business strategy are investigated, and results show that they do indeed relate to each other. Another finding was that the sampled forestry company, SCA centralised administrative functions to improve Internal control had affected their International business strategy positively and their international subsidiaries could focus on remaining main tasks. In conclusion, the forestry benefit from having centralised administrative functions to improve efficiency and decentralise departments such as sales to drive revenue abroad.
